Famous quotes containing the word age:
“Hath homely age th’ alluring beauty took
From my poor cheek? Then he hath wasted it.

If voluble and sharp discourse be marred,
Unkindness blunts it more than marble hard.”

For “Miss must not enquire too far into things, it would turn her brain; she had better mind her needlework, and such things as were useful for women; reading and poring on books would never get me a husband.””
—Sarah Fielding (1710–1768)
